So both battery systems is in ie. the old National Luna as well as the newly fitted HCDP 30A DC-DC. Both have new batteries as well and to top it off, I now have a 110A alternator compliments of Graham

Tested it - I think.....

All seems to be working fine so holding thumbs that there will be enough cold beer for the next two weeks as it seems that it will be HOT!!!

Tested the HCDP with the new 55L fridge fully loaded with warm "drinks" started up at full blast and then the battery still takes in an average of 12-15amps while driving. this is also whilst the National Luna system is running with the two 32L fridges on at full blast from warm.
